Exercise-8: Model

Introduction

Models are the heart of any JavaScript application, containing the interactive data as well as a large part of the logic surrounding it: conversions, validations, computed properties, and access control.

Solution

Include following code in 'main.js' and check conole.

var human = Backbone.Model.extend({
            initialize: function(){

                console.log("Model got initialized);

});

var person = new human; 

Using default value to set Model Attributes

Modify above code with following and check console.

var human = Backbone.Model.extend({

defaults: {

  name: 'Guest User',

  age: 23,

  occupation: 'Worker'



 },
initialize: function(){

                console.log("Model got initialized);

});

var person = new human; 
console.log(person.get('name'))


Using constructor to set Model Attributes

var human = new Person({ name: "Twomot", age: 01}); 
console.log(person.get('name')+'-'+console.log('age'));


Using getters / Setters

var human = new Person({ name: "Wipro"}); 
human.set('age', 23);


console.log(person.get('name')+'-'+console.log('age'));
